摘要
地理信息系统(GIS)已被广泛用于移动通信行业中的网络优化工作中。传统的GIS应用方式是以点的形式呈现各个发射基站的地理位置,缺乏各小区之间尤其是相邻小区之间关联关系的分析,不能很好地支持小区覆盖的直观表现,难以提供基站和直放站建设的决策支持。本文采用以Voronoi图为核心算法的小区模拟覆盖功能,可以按地理上的离散基站将通讯区域划分为小区,实现了小区物理覆盖情况的模拟,提高了GIS系统的地理分析功能和互操作性。
Abstract. GIS has been wildly applied in the network optimization work of mobile communication industry. Typical GIS application method mainly refers to the way that the geographic places of the radio base sites are taken on in the form of point which can not support efficiently the intuitionistic representation and is hard to supply the decision support the construction of the base site and the relay station. This paper takes Voronoi graphic as the core method of cell coverage simulation function, it can divide communication area into sub-area （cell） by geographically disperse base sites, This method improves the ability of geographical analyze and the co-operability between the user and system.
